Abstract

This document describes the encoding used in electronic mail [RFC822]

for transferring Hebrew. The standard devised makes use of MIME

[RFC1521] and ISO-8859-8.

Description

All Hebrew text when transferred via e-mail must first be translated

into ISO-8859-8, and then encoded using either Quoted-Printable

(preferable) or Base64, as defined in MIME.

The following table provides the four most common Hebrew encodings:
